"""MemoryFileNode Schema — vault domain "constitution".

Per `structure.md` §"全局架构蓝图", the Schema layer sits between the
domain-agnostic Core Engine and the three MemoryFileNode Services. Engines store
arbitrary markdown + open frontmatter dicts; Services read this Schema
to know what a "well-formed memory" is and shape the vault accordingly.

Public API:

    MemoryFileNode         — single typed class for every vault frontmatter
    Lifecycle / Scope / Source / Role  — the four behavioral axes (StrEnum)
    Status         — streaming-only state (active / distilled / archived)
    Confidence     — claim-only confidence (PENDING / VERIFIED / REJECTED)

    parse_frontmatter(raw) → (MemoryFileNode | None, errors)   tolerant parser

    *_PRESET dicts — common axis combos for hot-write paths
    preset_for_category(name) — legacy category → preset lookup

    LEGACY_AXES_FROM_CATEGORY — back-fill table; auto-applied by MemoryFileNode's
                                pre-validator so legacy vaults parse free.

Lives in `reme2/memory/` (not `reme2/schema/` and not `reme2/component/`)
because the Schema is owned by the memory services that consume it. The
engine never imports from here.
